C bus interface interrupt generation and continuous receive
Description
Stop Condition Interrupt Source Mask
Enables or disables the interrupt generation when the stop
condition is detected in slave mode.
0: Enables IRIC flag setting and interrupt generation when
1: Disables IRIC flag setting and interrupt generation when
Handshake Receive Operation Select
Enables or disables continuous receive operation in receive
mode.
0: Enables continuous receive operation
1: Disables continuous receive operation
When the HNDS bit is cleared to 0, receive operation is
performed continuously after data has been received
successfully while ICDRF flag is 0.
When the HNDS bit is set to 1, SCL is fixed to the low level
and the next data transfer is disabled after data has been
received successfully while the ICDRF flag is 0. The bus line
is released and next receive operation is enabled by reading
the receive data in ICDR.
the stop condition is detected (STOP = 1 or ESTP = 1) in
slave mode.
the stop condition is detected.
